[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Reference Figure 1-Figure 4 The utility model provides an embodiment of a water supply valve with a filtering function, comprising a valve body shell 1, a connecting pipe 3 is fixedly connected inside the valve body shell 1, a sealing assembly is arranged inside the connecting pipe 3 to prevent leakage of the connecting pipe 3, a filter screen 29 is slidably connected inside the connecting pipe 3, a mounting plate 5 is fixedly connected to the side wall of the filter screen 29, a mounting shell 9 is fixedly connected to the side wall of the mounting plate 5, a pull rod 6 is slidably connected inside the mounting shell 9, a handle 7 is fixedly connected to the upper surface of the pull rod 6, a fixed cylinder 10 is fixedly connected inside the mounting shell 9, a side wall of the pull rod 6 is slidably connected inside the fixed cylinder 10, and a side wall of the fixed cylinder 10 is fixed A sliding rod 11 is connected, and a sliding block 12 is slidably connected to the side wall of the sliding rod 11. A fixing ring 13 is fixedly connected to the side wall of the pull rod 6. A rotating bar 14 is rotatably connected to the side wall of the fixing ring 13. The side wall of the rotating bar 14 is rotatably connected to the side wall of the sliding block 12. A mounting block 8 is fixedly connected to the side wall of the connecting tube 3. The sealing assembly includes a sealing ring 4. The side wall of the sealing ring 4 is fixedly connected to the inside of the connecting tube 3. A first spring 15 is sleeved on the side wall of the pull rod 6. The side wall of the sliding block 12 is slidably connected to the inside of the mounting block 8. One end of the first spring 15 is fixedly connected to the inside of the mounting shell 9, and the other end of the first spring 15 is fixedly connected to the side wall of the fixing ring 13.
[0035] When operating the device for daily work, when the filter screen 29 needs to be disassembled, first, by pulling up the handle 7, it pulls the pull rod 6 to move upward, this action will drive the fixing ring 13 to move upward, and then apply pressure to the first spring 15, at the same time, the rotating bar 14 will also rotate accordingly, and the rotation of the rotating bar 14 will cause the sliding block 12 to slide toward the middle along the side wall of the sliding rod 11, and this sliding process will cause the sliding block 12 to detach from the inside of the mounting block 8. When the sliding block 12 detaches from the inside of the mounting block 8, the fixing effect between the mounting block 8 and the mounting shell 9 will disappear. At this time, the filter screen 29 can be easily taken out of the device for necessary cleaning and maintenance work. The sealing ring 4 installed in the connecting pipe 3 can effectively prevent leakage at the installation location of the filter screen 29, thereby improving the sealing of the equipment. Through this detachable filter screen 29, when the filter screen 29 needs to be replaced, it is easier and faster, which improves work efficiency, facilitates cleaning of impurities accumulated on the filter screen 29, reduces blockage and wear of the filter screen 29, and extends the service life of the valve.
[0036] Reference Figure 5-Figure 6 A clamping block 18 is fixedly connected inside the valve body shell 1, a sealing sleeve 19 is sleeved inside the valve body shell 1, a valve body shell 2 is arranged on the side wall of the valve body shell 1, a side wall of the clamping block 18 is slidably connected inside the valve body shell 2, a side wall of the sealing sleeve 19 fits inside the valve body shell 2, a mounting block 20 is fixedly connected to the side wall of the valve body shell 1, a mounting block 3 21 is fixedly connected to the side wall of the valve body shell 2, a rotating handle 16 is arranged inside the valve body shell 1, a ball valve 17 is fixedly connected to the lower surface of the rotating handle 16, a side wall of the ball valve 17 is rotatably connected inside the clamping block 18, and a sliding connection is made inside the mounting block 3 21 A sliding column 22 is movably connected, one end of the sliding column 22 is fixedly connected to a pressing strip 23, a side wall of the sliding column 22 is sleeved with a second spring 24, one end of the second spring 24 is fixedly connected to the side wall of the sliding column 22, and the other end of the second spring 24 is fixedly connected to the inside of the mounting block three 21, a push rod 25 is fixedly connected to the side wall of the sliding column 22, and a clamping block 26 is rotatably connected to the side wall of the push rod 25, and the side wall of the clamping block 26 is slidably connected to the inside of the mounting block 20, and a sliding groove 27 is provided inside the clamping block 26, and a fixed column 28 is fixedly connected to the inside of the mounting block three 21, and the side wall of the fixed column 28 is slidably connected to the inside of the sliding groove 27.
[0037] During the internal inspection of the valve, it is first necessary to press the pressing bar 23. This action will prompt the sliding column 22 to slide along the predetermined track. As the sliding column 22 moves, the second spring 24 will shrink. This shrinkage action further pushes the push rod 25 forward. The movement of the push rod 25 will drive the block 26 to slide accordingly inside the mounting block 20. As the block 26 slides, the fixing column 28 will also slide accordingly inside the slide groove 27. This series of sliding actions will eventually cause the block 26 to rotate. When the block 26 rotates to a certain angle, it will lose its fixing effect on the mounting block 20. At this time, the connection between the valve body shell 1 and the valve body shell 22 will be released, allowing the maintenance personnel to easily separate the two parts. After separation, maintenance personnel can easily carry out necessary inspection and maintenance work on the internal structure of the valve. This split design can make maintenance and repair work easier and more convenient, reduce disassembly steps, and improve work efficiency. A sealing sleeve 19 is installed between the valve body shell 1 and the valve body shell 2. The sealing sleeve 19 can make the valve body shell 1 and the valve body shell 2 closely contact to form a sealing layer, prevent medium leakage, and ensure the safety and stability of the pipeline system.
[0038] Working principle: When the device is used for work, when it is necessary to disassemble the filter screen 29, first pull the pull handle 7 to pull the pull rod 6 upward, thereby driving the fixing ring 13 to move upward to squeeze the first spring 15, and at the same time rotate the rotating bar 14, thereby pulling the sliding block 12 to slide toward the middle on the side wall of the sliding rod 11, so that it is separated from the inside of the mounting block 8, so that the mounting block 8 and the mounting shell 9 lose the fixing effect. At this time, the filter screen 29 can be taken out and cleaned and maintained. When it is necessary to inspect the inside of the valve, press the pressing bar 23 to slide the sliding column 22, so that the second spring 24 is contracted, and at the same time push the push rod 25 to move, so that the clamping block 26 slides inside the mounting block 20, so that the fixing column 28 slides inside the slide groove 27, and the clamping block 26 rotates, so that it loses the fixing effect on the mounting block 20. At this time, the valve body shell 1 and the valve body shell 2 2 can be separated, and the inside can be inspected and maintained.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
